1.7.0 is an upcoming major update focused on expanding the content from the Mega Man games already represented, namely, the eleven Mega Man numbered games. Unlike previous major updates, which were centered on implementing one or two Mega Man games, 1.7.0 aims to amplify the content of games already represented in Mega Man Maker.
The development team held an enemy contest where users could vote for an enemy to be added from the 8-bit styled Mega Man games, namely Mega Man 1, Mega Man 2, Mega Man 3, Mega Man 4, Mega Man 5, Mega Man 6, Mega Man 9, and Mega Man 10. The game selection was limited to the 8-bit games to ensure the development team could release the enemy in a "timely manner". The contest was also split up into two phases as "[t]he full list of potential enemies [was] too large to include in one poll". In phase 1, users would select the game the enemy was from and in phase 2, users would select an enemy from phase 1's winning game.
Phase 1 of the contest began on April 17, 2020 and ended on April 20, 2020. The most voted game was Mega Man 10—however, the winner was decided after "disregarding any illegitimate votes". Phase 2 of the contest began on April 20, 2020 and ended on April 23, 2020. Returning Machine Gun Joe received the most votes at 16.3%, however, it was already implemented before the contest began. To compensate for this, the development team decided to implement the second place winner, Neo Heli Metall, which received 14.6% of the votes. The total votes for phase 1 and 2 individually ended up being over 1000 votes.
